Capillaries do not have valves. Veins are the blood vessels with valves.
Valves are in the veins.
Arteries are valve-less vessels, meaning there are no valves.
Infection of vessels and heart valves is a special characteristic of C. fetus.
No, only venous vessels have valves. Valves in veins help prevent the backflow of blood and aid in promoting blood flow back to the heart. Arterial vessels do not have valves because blood in arteries is under higher pressure and flows away from the heart.
Only veins contain valves. The valves prevent the backward flow of blood.
passive
They have valves so that they can move lymphatic fluid much the same as veins by skeletal muscle contraction.
veins
